When it comes to providing great child care, this health care company takes the cake. Its seven on-site facilities treat kids under age 5 to puppet shows, storytelling, art, music and nature activities, and even offer kindergarten and summer camps in some areas. Parents can swing by as early as 7 a.m. and pick children up as late as 6:30 p.m.; if little ones feel under the weather, a nurse will tend to them. It’s perfect for school holidays or backup care (employees get up to 20 uses annually), as the centers are open year-round. Tuition discounts and waived registration fees are also variously available at facilities run by eight external providers, making child care more affordable for parents who work from home or live in more remote locations.
